The point of using the Contour ShuttlePro is the programmable buttons. You have 13 buttons to define as you wish, and they can do different things by screen. The jog wheel in the middle can always adjust volume. I can navigate between skins, control functions such as next, previous, mute, vol+, vol-, etc. without ever looking at the screen. I also use it to control winamp directly, outside of RR. Just about everything you want to do in winamp has a keyboard shortcut which can be assigned to a button or jog wheel.
